Obviously a Dark Wizard, Yet They Call Me a Saint?

Sallen transmigrates into a fantasy world, becoming a dark wizard apprentice with a unique system that grants rewards only when he saves others. From the "Lesser Active Potion," which boosts magical affinity and accelerates meditation, to the extinct "Mad Whispers" limit-breaking potion; from the "Dragon Devourer" talent, which infinitely strengthens the body by consuming dragon flesh, to the "Dragon Sovereign" talent, which commands a dragon's life and death with a single word (Dragon God? Just devour it!), alongside legendary wizard tools ranging from "Ancient Secret Treasures" to "Forbidden Myths," his power grows exponentially. He also discovers other clever uses for his cheat system. For instance, when a red glow appears from a companion's chest, Sallen simply knits his brows and retreats behind the others. Alternatively, if an enemy who was meant to die at his hands is spared under false pretenses, he can exploit the system to double-dip on rewards. "Have you heard? The Shadow School has produced a 'Merciful' Sallen." "Tch! He's nothing more than scum among dark wizards! I bet he'll be killed by the Alliance's bounty hunters next time!" Nearby, the man himself, Sallen, sips his red tea and gently shakes his head. They actually take him for a bleeding-heart saint?
